TIME METERING CHARGE FOR TELEPHONE SERVICES.

SPECIFICATION forming part of Letters Patent No. 774,082, dated November 1, 1904. Application filed May 17, 1904:. Serial No. 208A91. (N0 model.)

To (all whom, it may concern:

Be it known that I, ISIDOR KrrsEE, of the city and county of Philadelphia, State of Pennsylvania, have inventedcertain new and useful Improvements in Metering Charges for Telephone Services, (Case No. 188,) of which the following is a specification.

My invention relates to an improvement in metering the charge for telephone service. Its object is to automatically register at places more or less remote from the place of operation the charge for the time service of an outlying station. In devising an apparatus adapted to automatically register such charge it is necessary to take into consideration that the companies existing to -.day have a certain charge rate for the first unit of time and a different charge rate for all additional units of time and also that such companies have one charge rate for day service and another charge rate for night service for one and the same distance.

As in the general practice of to-day the outlying circuits center in one common exchange and are connected therein through a so-called connecting-cordfa device capable of automatically registering should also take into consideration that only the party calling up is charged with the service, whereas the party called is free from any charge, and in devising such an apparatus 1 have taken into consideration all these points.

The underlying principle of my invention consists in the employment of what I call contact-wheels, one or more for each group of charge rates, each group embracing the rate for the first unit of time for day as Well as night and the additional units of time for day as well as night. Each Wheel therefore embraces four series of contacts, one series representing the charge for the first unit of time for day, one series representing the charge for the first unit of time for night, one series representing the charge for the additional time units for day, and one series representing the charge for the additional time units for night, and for better understanding I have selected as an illustration a contact-wheel adapted to register a local service at the rate of ten cents for the first unit of time-by day and six cents for the first unit of time by night and at the rate of six cents for each additional unit of time by day and four cents for each additional unit of time by night, and I have elected that the contacts representing the charge for the first unit of time by day as well as night should be onthe face of said wheel, and that the contacts representing the charge for the additional units of time by day shall be on one side, and that the contactsrepresenting the charge for the additional units of time by night shall be on the other side of the wheel.

Referring now to the drawings, Figure 1 is a perspective view of a contact-wheel. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation of Fig. 1, showing the manner in which this wheel is mounted on the shaft. Fig. 4. is a side elevation of the frictional wheel securely fastened to the shaft and always revolving with same. Fig. 5 is a side view of Fig. 3, illustrating the face as well as the side brushes for night. Fig. 6 is a diagrammatic view illustrating the electrical connections of the source of current adapted to actuate the metering device in an outlying station adapted to be connected to a second outlying station through one kind of connecting-cord. Fig. 7 is a similar view wherein a different connecting-cord is used and wherein means are provided to notify the operator when the conversation has ceased.

A is the contact-wheel as an entirety, of which A is the face and A and A respectively, the two sides thereof. The face A is provided with the contacts 1, 2, 3, 4, 5, 6, 7 8, 9, and 10, the contacts 1 to 6, inclusive, extending the full width of the face and the contacts 7 to 10, inclusive, extending only part ofthe-face of said wheel. On the side A of the wheel are the contacts 1, 2, 3, 4, 5, and 6*,and on the side A of the wheel are the contacts 1", 2 3 and 41 The wheel is provided with the center hole B and on one side with the corrugations C. The Wheel is also provided with the protrudence D and the groove (0. (Shown in Fig. 5.) In reality the wheel may consist of metal, and the surface may be provided with insulating material on such places where it is desired that the brush shall not come in contact with conducting material. The Wheel is mounted on the shaft E in juxtaposition to the friction-wheel F and is pressed with one side against this wheel by the spring Gr. To counteract this pressure, there is provided the lever H, with the revoluble wedge I. (Shown in position in Fig. 3.) The wheel itself is loosely mounted on the shaft, so that it may either revolve or be kept stationary, no matter if the shaft is revolving or not, as long as this wedge I keeps apart the corrugated surface 0 from the friction part F. The brush J is designed to make connection with all ten contacts on the face A of the wheel, and the brush K is designed to make connection With the contacts 1 to 6 on said face during each revolution of said wheel.

In electrical connection with the brush J is the brush J, adapted to make contact with every one of the six contacts on the side A of the wheel during each revolution of the same, and the brush K is in electrical contact with the brush K, designed to come in contact with each of the four contacts on the side A during each revolution of the wheel.

The lever H is operatively connected, but insulated from the lever L, which lever is held in position, as shown in Fig. 5. by the spring M, so as to rest with the point m on the insulated portion a of the block W.

In Fig. 6, O is the outlying station provided with the lever P, which lever is provided with the contact 3), insulated therefrom, but in electrical contact with wire 12. This wire 12 is in permanent connection, through the coil of electromagnet S, with wire 13, and to this wire 13 is connected, with the interposition of the resistance R, the coil S of the metering device T. The other terminal of this coil is grounded at Z. To Wire 12 is also connected one terminal of the coil of electromagnet S and one terminal of the coil of electromagnet S. The electromagnet S is provided with the armature 8, adapted to come in contact with the wire 13, thereby establishing a circuit including the coil of electromagnet S ,.and the coil of electromagnet S is provided with the armature 8 also adapted to make contact with wire 13, thereby establishing a circuit including the two coils of electromagnet S". These coils are provided with the common armature s normally resting against the wire 14, connected to one terminal of the electromagnet S, and the armature itself is connected, through wire 15, with the other terminal of said electromagnet, thereby estab lishing a shunt around said electromagnet. The outlying station 0 centers through wires 16 and 17 in the exchange and is connected therein with the interposition of the necessary devices to the different jacks in the switchboards. One of these jacks is here designated at U. The connection of this outlying circuit to a second circuit is made through the insertion of one of the plugs in the circuit calling and through the second of the plugs in the circuit called.--v These plugs are connected to each other through the connectingcord. This connecting-cord is here designated as an entirety by the letter V and consists of the wires 18 and 19. The wire 18 may be constructed as usual; but the wire 19 has inserted therein the wires 20 and 21, terminating in the plug V. This plug consists of the plug proper and the catch Q}, insulated from the plug at the point where it is attached thereto, but normally in contact with the plug through the part a, and being of such construction that this part Q. can easily be raised from the plug proper, thereby breaking connection between the wire 20 and 21.

The shaft E is in electrical connection, through the brush 0, with the source of current W, grounded at Z, and the conducting part N is in electrical contact with the source W, grounded at Z. The lever L is provided with the two recesses Z' and Z, adapted to receive the plug V. The recess Z is in electrical connection, through wire 22, with the brushes J and J, and the recess Z is in electrical connection, through wire 23, with the brushes K and K. In Figs. 6 and 7 the shaft is provided with the three wheels A AA, each wheel to be provided with the necessary contacts to suit requirements, but not shown here.

I will now describe'the modzm oparmzdz' of this part of my invention: At the central station, under the care of the operators having in charge a series of outlying stations, is located the contacting device, consisting, broadly, as stated above, of the shaft E, revolved by the suitable means Q. This shaft is designed to make one revolution in aspace of time allowed by the company for one charge. It is supposed that the time unit for one charge is three minutes. The shaft therefore has to make every three minutes one revolution. It was also stated above that the contact-Wheels are loosely mounted on the shaft, but are provided with means whereby they are closely pressed against the frictionwheel securely mounted on the shaft, and that as long as they are in close contact with the friction-wheel their movement will correspond entirely with the movement of the shaft E, but when the device is out of use the pressure of the spring is counteracted by the revoluble wedge I, attached to the lever H. This wedge is, with the aid of this lever and lever L, pressed in between the contactwheel proper and the friction device mounted securely on the shaft E. The wheel will still revolve approximately at the same speed as the shaft; but when the wheel is in a position so that the groove (6 will come opposite to the upright L the upper part of this upright will fall into this groove, and will thereby estop the Wheel from further movement. Thus it will be seen that each wheel Will stop at a predetermined position, and this position is such that the brushes J and K will be near the broad contact 1-that is, the first contact to be made for the metering of the charge of a call. Normally, therefore-that is, when the device is entirely out of use-the shaft E will revolve at the usual speedthat is, one revolution every three minutes but the wheels secured to said shaft will remain stationary. It is now supposed that the subscriber at O has requested to be connected to a second subscriber and that the operator has connected both subscribers through the device V. At the moment of connection the operator places the plug V if in day-time, in the recess Z, and if at night in the recess Z, of one or the other of said wheels in accordance with the rate charge for the time unit. It is supposed here that the conversation takesplace in the day-time between two subscribers of one city, and it is further supposed that the rate for the first time unit is ten cents and six cents for each additional threeminutes; Therefore the plug will be inserted in the recess l of the first wheel A, which has the contacts as outlined in Figs. 1 and 3. Through the insertion of this plug the near end of the lever L will be pressed upward, moving the farther end of the lever L, with its appended lever H and wedge I, downward, thereby removing the means which counteracted the spring G,

and as at the same time the upper part of theupright L will be removed-from the groove a it is obvious that the wheel pressed by the spring G against the friction device F will now have to follow the movement of the shaft E. It will be noticed that the separate contacts on the face of the wheel designed to represent the charge of the first time unit are very close to each other and are near the point from where the wheel starts when released from its locking device and that these contacts only occupy a small part of the whole circumference of the wheel, this for the reason that if the subscriber only uses part of the time unit-that is, part of the allotted three minuteshe is still charged with the whole rate-that is, ten cents-and this ten cents must be registered for the shortest possible connection. -Through the insertion ofthe plug V a circuit will be established between the grounded source of current W at the exchange and the grounded metering device at the subscribers station 0 as often as the brush J comes in contact with one or the other of the contacts 1 to 10; but as both the calling subscriber at O and the subscriber called are in electrical connection with each other through the connecting device V, and as each of these subscribers is provided with a metering device the electrical connection between the metering device and the grounded source of current W will be established not only at the station 0, but also at the station of the subscriber called, an action desired to be avoided, and forthis purpose I have recourse to the following arrangement: As was pointed out in the description of the drawings, the metering device at the subscribers station is normally inoperative, for the reason that its electromagnet is shunted, and it is the face of the wheel is of a width greater even than the width of three or four of the separate contacts following and of a width suflicient so as to continue the flow of the current necessary to fulfil all these operations, and thereby make operative the metering device. The operator by placing the plug V in the recess Z presses against the device in a manner so as to break the continuity between the part 0) and the plug proper. This will break the electrical continuity of the wire 19 of the circuit of the plug V and will allow the first impulse of long duration only to flow over the line 16 of the subscriber 0, thereby actuating all the electromagnetic devices and making operative the metering device at this station, but leaving the metering device of the station called in its normal that is, inoperativestate. The period it takes to perform this operation will easily be ascertained in practice, and the operator has only to keep the device V from connecting electrically with the plug V till this operation is ended, a period lasting not more than two or three seconds. The time for making the subsequent contacts is of such short duration that it will not suffice to produce the effect of the first broad contact-that is, to make operative that metering device which so far remains inoperative-and all the subsequent impulses will therefore only actuate the metering device of subscriber 0. It is true that as soon as the connection with the first broad contact is broken the electromagnets S, S and S will be deenergized and the armatures of the electromagnets S and S will be drawn away from their cores, and therefore from their contacts; but the electromagnet S is constructed in amanner so that even if the current ceases the armature will remain in the position into which the first current impulse has forced it, and the shunt, therefore, of the metering device will remain open. In reality the electromagnet S consists of the two electromagnetic coils provided with one common polarized armature in a manner so that it requires a reversal of the current to return the armature again to its normal position. It is supposed that the conversation between the in Fig. 5 and revolving at the rate of three minutes for each revolution will near the end of these three minutes be with that part of the circumferenceopposite the brush J which is provided with the protrudenee D, and as soon as the brush J encounters this protrudence it will be thrown upward, and as this brush is operatively connected with the brush J it is obvious that the brush J will be lifted to an extent so as to come in contact with that part of the side periphery which is provided with the contacts for the additional time units--that is, the contacts 1 to 6, inclusive. It is now supposed that the conversation continues longer than the allotted three minutes. The brush J, which was lifted by the protrudence D from off the face of the wheel, will remain in this position, as it is frictionally pivoted ata, and it will therefore ceaseto make connection with any of the contacts on the face of said wheel; butthe brush J, which formerly only touched that part of the side of the wheel which was void of any contacts, is now in such a position that it connects dur ing the progress of the movement of said wheel with one or more of the contacts l to 6 on the side A of said wheel; but, whereas the contacts on the face of the wheel denoting the first time unit are close to each other, for the purpose as stated above, the contacts on the side A are distributed around the whole periphery of said side, for the reason that only such part of the additional time unit as is actually consumed by the conversation is charged to the subscriber calling. It is now supposed that after one and one-half minutes over the first time unit the conversation ceases. Therefore the wheel has in all made, first, one full revolution, during which time the brush J made connection with ten contacts, thereby actuating the metering device ten times; second, one-half revolution, during which time the brush J made connection with one-half of the six contacts distributed at equal distances around the periphery of the side Athat is, has made connection only with contacts 1, 2", and 3, thereby actuating the metering device three times, making in all thirteen times, and as each actuation registers the value of one cent it is obvious that these thirteen actuations will register the value of thirteen cents, and this is exactly the value charged for four and onehalf minutes continuous conversation. It is now supposed that the conversation has ceased and that the operator removes the plug 0) from the recess Z. The lever L will be returned to its position through the action of the spring M, and as thepivoted partof the spring rests, through the upright (6 on the lever L it is obvious that the brushes will again resume their former position. The wheel will be again pressed away from the frictional de vice F, but will still revolve so long till the groove (0 comes opposite the upper point of the upright L, when this upper point will fall into the groove a, thereby arresting the further action of said wheel; but at the subscribcrs station the metering device will still be in an operative position, and it is necessary to make the same inoperative. This I. accomplish by sending an impulse of opposite polarity through the grounded leg at the subscribers station 0, and for this reason I have connected to the conducting part N the battery IV, grounded also at Z, which battery is oppositely connected from the battery The operator after withdrawing the plug V from the recess 6 touches the conducting part of N with the pointof the plug, thereby transmitting an impulse in opposition to the impulses formerly transmittel, and this impulse of opposite direction will throw the armature 8 again to its normal positionthat is, the position as shown in Fig. 6whereby this armature completes a shunt around the electromagnet of the metering device, thereby making this device inoperative. These, in general, outlines are the operations necessary for metering the exact value of a call made by an outlyingsubscriber; Should this call be at night instead of in the day-time, then, as above stated, the plug has to be placed in the recess Z, which registers the night rate of the first unit, as well as additional time units. In other respects all the operations are the same as if the conversation would take place in the day-time.

In some cases the connecting-plug consists of two parts inductively related to each other, but electrically not connected. In such cases the intermediate devices S, S and S at the subscribers station are not necessary; but it would be of great advantage should the operator, through an annuneiating device -such, for instance, as the lighting of a lamp-be notified that the conversation has ceased and that the plug now should be removed, and in Fig. 7 I have illustrated this modification. In this figure instead of placing the plug V in series with the cord of the main plug it is only necessary to connect the plug V with the cord of the plug V, as is illustrated in this figure, and to place at the subscribers station only the metering device T, with its electromagnet S, for the reason that it is now unnecessary to guard against the working of the metering deviceat the station of the subscriber called. In this arrangement it is also unnecessary for the operator to send an impulse over the line in opposition to the impulse adapted to actuate the metering device, and therefore the source of current IN is not required. As stated above, I have illustrated in this figure the means for notifying the operator when the conversation has ceased, and this means consists of a source of current grounded at Z and connected with the other pole to the electromagnetic device Y, provided with the weighted armature 1 to the pivoting-point of which the second tercient. to energize it.

minal of the electromagnet Y is connected. In proximity to this armature is the terminal of the source of current W the other terminal of which is connected to the lamp X, connected, through wire 24, with the point e and the point 1? adapted to make contact with the collar V of the plug V if this plug is in positionthat is, is inserted in one or the other of the recesses Z or Z. The armature y is connected, through wire 25, to the conductingblock N. As long as the plug is out of position that is, is notinserted in either of the recesses-the circuit of the battery W is broken, as the terminals of the two wires 2e and 25 are out of electrical contact; but as soon as the plugV is inserted in the recess Z or Z the collar V connects with one of the points 01 or v and as the plug also connects with the conducting-block N it is obvious that the circuit between 24 and 25 is established, thereby making operative the lamp X; but at the same time as the'plug V is connected with the leg 16 of the circuit of station 0 and as the subscriber has, through the removing of his receiver from the hook, connected this leg with the ground Z at his station it is obvious that the path is also established for the source of current W and as in the circuit of this battery the electromagnet Y is placed and is therefore energized the armature y will be drawn toward the core and away from the point forming one terminal of the battery W thereby breaking the circuit of this battery and making the lamp X again inoperative; but should the subscriber place his receiver on the hook the circuit of the leg 16 with the ground Z will be broken, thereby breaking the circuit of the battery W and deenergizing the electromagnet Y, which in turn will result therein that the armature y will return to its position in contact with the terminal of the battery W making again a circuit including the lamp X, lighting the same, and this lighting will notify the operator that the conversation has ceased and both the plugs V and V should be removed from their positions. Through the removal of the plug V the circuit including the battery W will again be broken and the lamp extinguished. The electromagnet Y is of such construction that even a feeble current, such as is generated by one battery, may energize its core to an extent necessary to draw the armature toward the same; but the magnet S of the metering device T should be of such construction that the feeble current from W will not be sufii- I In other words, the feeble current of W should not interfere with the strong impulses of the source of current W or the operation of the device adapted to be actuated through such impulses. It will be noticed that the armature y is minus a spring, but has a counterbalance which may be regulated so as to give this armature the sensitiveness not possessed by the armature of the metering device T. I have not in this figure or in Fig. 6 illustrated the necessary devices at the subscribers station or the devices neccssary to be included in the subscriber or plug circuits, as these do not form part of my invention. It is obvious that should it be desired a metering device maybe placed in connection with this system, also at the exchange, so that not only the subscriber, but also the proper oflicer at the exchange, shall at a glance be able to see the status of telephonic service for this subscriber. If such meter is placed for each subscriber at the exchange, it is best to place all the meters in one room and at one or more metering-boards.

I have in the description of Fig. 6 noted that it is necessary after the conversation has ceased and the subscriber has,through the replacing of his receiver on the hook, broken the contact between wire 16 and wire 12 to send one impulse over the line for the purpose of returning the armature of electromagnet S to its normal position, so as to make the electromagnet S of the metering device T inoperative. As the electrical contact between these two wires is broken, it is necessary to provide means whereby that impulse may fiow through the coil of electromagnet S and for this reason I have provided the condenser P, shunting the gap between wire 16 and wire 12, and I have constructed the coils of the magnet S so that these coils should answer to an impulse of high potential, but short duration. The source W therefore should be able to charge the condenser P to an extent so that the discharge of said condenser should be able to actuate the electromagnet S In Fig. 7 such impulse is unnecessary, and this condenser P is therefore omitted in said figure, and I have only in conventional signs illustrated the condenser and bell as now employed in multiple are between the legs of the subscribers circuit.

It is obvious that the annunciating device can be employed with the arrangement as illustrated in Fig. 6 as well as with the arrangement shown in Fig. 7
